Just putting Sam down for a nap never seems like a good idea to him. He would prefer you to cuddle him up close to you and bounce him until he is all the way into dreamland. And then if he wakes, could you please start the whole process over?
Here we are mid-morning yesterday. He's wrapped snug in my sling, and I've replaced my computer chair with an exercise ball - which, by the way, is the greatest baby tool in the whole world. Near-effortless highly-effective bouncing.
